Ugreen UG-15612 HiTune H5 True Wireless Earbuds

The Ugreen HiTune H5 (Model WS201/UG-15612) delivers premium audio quality through large 13.6mm bio-diaphragm drivers in a true wireless design. These semi-in-ear earbuds combine AI-powered call noise reduction with Bluetooth 5.3 connectivity for reliable daily use.

Large 13.6mm Bio-Diaphragm Drivers

The UG-15612 features oversized 13.6mm dynamic drivers with bio-diaphragm construction. This large driver diameter exceeds standard earbud drivers by significant margin. The bio-diaphragm material provides enhanced acoustic properties across the full frequency spectrum.

Low-frequency reproduction delivers strong and powerful bass response without distortion. Mid-range frequencies maintain vibrant and detailed presence for vocals and instruments. High-frequency treble remains bright and crisp for cymbal crashes and high-pitched sounds.

The large driver size enables greater air displacement for improved bass impact. Driver construction balances power handling with transient response speed.

Bluetooth 5.3 Technology

Bluetooth 5.3 technology provides enhanced wireless connectivity over previous Bluetooth generations. The UG-15612 operates across the 2400MHz-2483.5MHz frequency band with stable signal transmission. Maximum wireless range reaches 10 meters (33 feet) under optimal conditions without physical obstructions.

Low-Latency Gaming Mode

Gaming mode reduces audio latency to below 100 milliseconds for improved audio-visual synchronization. This ultra-low latency minimizes the delay between on-screen action and corresponding audio cues. Competitive gaming benefits from faster audio response that enables quicker reaction to in-game events.

The reduced latency mode proves valuable beyond gaming applications. Video streaming, movie watching, and video editing all benefit from tighter audio-visual alignment. Standard music listening uses normal latency mode to optimize battery efficiency. Users can switch between modes based on content requirements.
